CAR-TRUCK.

Specification of Letters Patent. Patented 1)(:50I 14 1920 Application filed January 24, 1920. Serial No. 353,646.

To all fw hom t may concern:

Be it known that I, JAMES D. BENBOW, a citizen of the United States, and a resident of Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in that class of cars particularly designed for use by contractors when building or repairing railroads and has particularlv to do with the construction of the truck of such a car whereby the truck may be adapted for use in supporting a rocking or tiltable dumping body or one or more receptacles that can be lifted by power on to and off of the truck.l or that may be coupled together in pairs and in spaced relation to each other by` a comparatively long load-supporting platform adapted to carry articles of too great length Y to be suitably placed upon a single truck. By

reason of the convertible character of the vtruck avery considerable saving to a contractor may be effected as it reduces the amount of rolling stock needed to be kept on hand for the hauling of different classes of road-building materials.

In the drawings,-

Figure 1 is a side elevation of a dumpcar embodying my improvements;

Fig. 2 is an end view of the body of the dump car shown in Fig. 1, and showing in section (the section being at line v2--2 of Fig. 1) the frame of the car-truckrand a portion of the supporting means that rises therefrom for pivotally securing said body in place;

Fig. 3 is a top plan view of the truck,- the car-body supports being shown in section;

Fig. 4 is a detail, being an enlarged perspective view of a corner portion of the truck frame and the car body supporting means connected to the truck frame at such corner;

Fig. 5 is a side elevation of two of the trucks connected in tandem fashion by means of a comparatively long load-supporting frame that is pivotally connected to the central portion of each truck frame,the car-body supports in this arrangement of the trucks being omitted.; and Y.

Fig. 6 is a side elevation of one of the trucks from which the body supports have been removed, as in Fig. 5, to adapt the truck to carry, as shown in this view, one or more removable receptacles.

Referring to the several figures of the drawings,-10 indicates the side bars of the truck frame, preferably formed of channelirons as shown, such side bars being connected together by heavy cross-bars 11 also formed of channel-irons and riveted to the bars 10 and each located a short distance from one 'end of the truck, as clearly indicated by broken lines in Fig. l. The side bars l0 are further connected at approximately their central portions by two separated bars 12 that constitute a bolster, upon the central portion of which is riveted the raised bearing plate 13 that coperates with one of the two Corresponding bearings on the under side of the truck connecting frame shown in Fig. 5 and hereinafter more particularly referred to. rlhe ends of the truck frame are each built up with heavy metal plates 14 and 15 that lie respectively against the upper and lower flanges of the side bars 10 and `cross-bars 1l, to which members l0 and 11 said plates are riveted. These upper and lower end plates give to the frame great rigidity and contribute greatly to the life of the frame by enabling the car to resist bumper shocks in hauling. The two inner corners of each up er plate 14 are cut away, as best shown in Blig. 3, to provide openings 16. 17, 17 indicate two Vcar-body supports located at opposite end portions of the truck frame and rising therefrom suiiiciently high to support between them in a rocking manner a car-body A adapted to turn so as to discharge its load at either side. Such car-body, by itself, forms no part of my present invention nor do the means for locking it in place, and hence no detailed description thereof is deemed necessary. Each car-body support, in the construction shown, comprises an angle-iron. strip bent to form a member having a curved central portion a upon which one end of the car-body is rockingly mounted and from which diverge downwardly two arms o, b, that terminate in vertical ends c, c, respectively. (See Fig. 2). Each of these vertical end portions projects through one Yof the openings V16 in an upper end plate and cross-bar 11,-see Figs. 3 and 4. 18 indicates a bracing member at each corner of the truck frame, each of such members 18 serving to vconnect an arm of a support 17 with the adjacent end portion of one of the side bars 10. Each bracing member 18, in the construction illustrated, is formed of a heavy flat metal plate that along its inner margin rests upon and is riveted to the outer face of one of the diagonal arms 'b and at its lower margin is turned outward to4 form a Harige 19 that rests upon the upper flange of the adjacent side bar 10 te which it is also riveted,-see Fig. 4. As will be appreciated these bracing members 18 so secure the supports 17 that the latter are securely held in place notwithstanding the severe shocks and strains that the car as a whole is subjected to in service. The coupling heads are indicated by 22 and as shown project from between the upper and lower plates 14 and 15, the inner end portion or shank ,member of each passing through an opening in the web of the adjacent channeliron cross-bar 11 `and having secured on the part that extends beyond said cross-bar a heavyv coiled spring 28 that bears against the face of said cross-bar. The bracing effect of the plates 14 and 15 will assist very materially in maintaining the rigidity' of the frame as a whole and in resisting the strains put upon the cross-bar during the Y hauling of the car.

If it be desiredto use the truck for other purposes Vthan supporting a tilting car-body such as shown in Figs. 1 and 2, the car-body can be removed by the use of a crane, and then if the supports 17 and bracing members 18 are found to be an obstruction to the desired use of the truck such parts 17 and 18 can be removed by cutting and punching out the `rivets that secure them to the truck frame, which is an operation ca able of being done with comparative ease with the tools and apparatus that will crdinarily form part of the equipment of a road-building contractor, and such supports and bracing members can likewise be refastenedin place with equal readiness when it is again desired to use the car-body on the truck.V While bolts might be used in place of such rivets I do not recommend their use, for with the rough usage to which the trucks are necessarily subjected the rivcts are much more dependable fastening devices and such dependability outweighs in importance the relative difficulty of removing and replacing rivets and bolts. Of course each support 17 will at all times have its bracing members 18, 18 connected to itV-the support and its two bracing members being treated as a unit for removal and replacement purposes. Vhile these units, each composed of the parts 1.7 and 18, are securely fastened in place as describer and would not therefore ordinarily bedescribed as removable, yet as it is contem consider those parts as members that are re-l movable from the truck proper.

In Figs. 5 and 6 I have shown two instances where the trucks with their bodysupports 17 and braces 18. removed are advantageously employed. In Fig. 5 two trucks spaced a distance apart are connected up by a comparatively long load-supporting platform 2O adapted to receive rails, telegraph-poles or other long articles, and in Fig. 6 each truck furnishes a support for one or more heavy receptacles such as contractors batch boxes which rest upon the side bars and end cross-bars of the truck and are adapted to be lifted on and off by a crane as usual. In the construction of Fig. 5 where two trucks are arranged spaced apart and connected lthrough the plattform 20 the center bearings 13 of each truck cooperate with similar bearings 21 secured to the under face of said platform 20, through registering'holes in each pair of bearings passing a king bolt,the connected trucks being thereby permitted to rindependentlyl follow the curves of the railway track to the same extent as if their drawheads were con-V nected together in the usual manner.

By my improvements I provide a strong and simple construction for supporting a dump-carbody upon a truck and one that,

upon the removal of such body and its sup-` porting devices, leaves the truck incendi tion to be immediately availed of for the transportation of other articles used in the work of road-building contractors and not adapted to be carried in a tiltable car-body.
